SAFETY INSTRUCTIONS
EYE PROTECTION which conforms to ANSI specifications and provides protection against flying particles
both from the FRONT and SIDE should ALWAYS be worn by the operator and others in the work area when
loading, operating or servicing this tool. Eye protection is required to guard against flying fasteners and
debris, which could cause severe eye injury.
The employer and/or user must ensure that proper eye protection is worn. Eye protection equipment must
conform to the requirements of the American National Standards Institute, ANSI Z87.1-1989 and provide
both frontal and side protection. NOTE: Non-side shielded spectacles and face shields alone do not
provide adequate protection.
CAUTION:
ADDITIONAL SAFETY PROTECTION
will be required in some environments. For example, the
working area may include exposure to noise level which can lead to hearing damage. The employer and user
must ensure that any necessary hearing protection is provided and used by the operator and others in the
work area. Some environments will require the use of head protection equipment. When required, the
employer and user must ensure that head protection conforming to ANSI Z89.1 1986 is used.
AIR SUPPLY AND CONNECTIONS
Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as tool may
explode, possibly causing injury.
Do not use supply sources which can potentially exceed 200 P.S.I.G. as tool may burst, possibly causing
injury.
The connector on the tool must not hold pressure when air supply is disconnected. If a wrong fitting is
used, the tool can remain charged with air after disconnecting and thus will be able to drive a fastener even
after the air line is disconnected possibly causing injury.
Do not pull trigger or depress contact arm while connected to the air supply as the tool may cycle, possibly
causing injury.
Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing the tool; 3.) When clearing
a jam; 4.) When tool is not in use; 5.) When moving to a different work area, as accidental actuation may
occur, possibly causing injury.
LOADING TOOL
When loading tool: 1.) Never place a hand or any part of body in fastener discharge area of tool; 2.) Never
point tool at anyone; 3.) Do not pull the trigger or depress the trip as accidental actuation may occur,
possibly causing injury.
OPERATION
Always handle the tool with care: 1.) Never engage in horseplay; 2.) Never pull the trigger unless nose
is directed toward the work; 3.) Keep others a safe distance from the tool while tool is in operation as
accidental actuation may occur, possibly causing injury.
The operator must not hold the trigger pulled on contact arm tools except during fastening operation
as serious injury could result if the trip accidentally contacted someone or something, causing the tool
to cycle.
Keep hands and body away from the discharge area of the tool. A contact arm tool may bounce from the
recoil of driving a fastener and an unwanted second fastener may be driven possibly causing injury.
Check operation of the contact arm mechanism frequently. Do not use the tool if the arm is not working
correctly as accidental driving of a fastener may result. Do not interfere with the proper operation of the
contact arm mechanism.
Do not drive fasteners on top of other fasteners or with the tool at an overly steep angle as this may cause
deflection of fasteners which could cause injury.
Do not drive fasteners close to the edge of the work piece as the wood may split, allowing the fastener to
be deflected possibly causing injury.
MAINTAINING THE TOOL
When working on air tools note the warnings in this manual and use extra care when evaluating problem
tools.

T55 TOOL SPECIFICATIONS
All screws and nuts are metric.
FASTENER SPECIFICATIONS:
TOOL AIR FITTING:
This tool uses a free-flow connector plug, 1/4” N.P.T. The minimum inside diameter should be .200” (5mm).
The fitting must be capable of discharging tool air pressure when disconnected from the air supply.
OPERATING PRESSURE:
The operating pressure of the T55 tool is 70 to 100 p.s.i. (4.9 to 7.1 kg/cm
2
). Select the operating pressure within
this range for best fastener performance. DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.
AIR CONSUMPTION:
Model T55 requires 2.8 cubic feet per minute (.08 cubic meters) of free air to operate at the rate of 60
fasteners per minute, at 80 p.s.i. (5.6kg/cm2). Take the actual rate at which the tool will be run to determine the
amount of air required. For instance, if your fastener usage averages 30 fasteners per minute, you need 50% of
the tool's c.f.m. of free air which is required for running at 60 fasteners per minute.

STANLEY-BOSTITCH OFFERS THREE TYPES OF OPERATION FOR THIS SERIES TOOL.
CONTACT TRIP
The common operating procedure on “Contact Trip” tools is for the operator to contact the work to actuate the trip
mechanism while keeping the trigger pulled, thus driving a fastener each time the work is contacted. This will allow
rapid fastener placement on many jobs, such as sheathing, decking and pallet assembly.
All pneumatic tools are subject to recoil when driving fasteners. The tool may bounce, releasing the trip, and if
unintentionally allowed to recontact the work surface with the trigger still actuated (finger still holding trigger pulled)
an unwanted second fastener will be driven.
SEQUENTIAL TRIP
The Sequential Trip requires the operator to hold the tool against the work before pulling the trigger. This makes
accurate fastener placement easier, for instance on framing, toe nailing and crating applications.
The Sequential Trip allows exact fastener location without the possibility of driving a second fastener on recoil, as
described under “Contact Trip”.
The Sequential Trip Tool has a positive safety advantage because it will not accidentally drive a fastener if the tool
is contacted against the work – or anything else – while the operator is holding the trigger pulled.
TRIGGER OPERATED
The Trigger Operated model is cycled by actuation of the trigger only. This model does not have a Contact Arm
and is intended for use only where a Contact Arm CANNOT be used to satisfy the requirements of the application.
The Trigger Operated tool will cycle each time the trigger is actuated.

AIR SUPPLY AND CONNECTIONS
Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as
tool may explode, possibly causing injury.
FITTINGS:
Install a male plug on the tool which is free flowing and which will release air pressure from the tool when
disconnected from the supply source.
HOSES:
Air hoses should have a minimum of 150 p.s.i. (10.6 kg/cm
2
) working pressure rating or 150 percent of the
maximum pressure that could be produced in the air system. The supply hose should contain a fitting that will
provide “quick disconnecting” from the male plug on the tool.
SUPPLY SOURCE:
Use only clean regulated compressed air as a power source for this tool. NEVER USE OXYGEN, COMBUSTIBLE
GASES, OR BOTTLED GASES, AS A POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE.
REGULATOR:
A pressure regulator with an operating pressure of 0 - 125 p.s.i. (0 - 8.79 KG/CM
2
) is required to control the
operatiing pressure for safe operation of this tool. Do not connect this tool to air pressure which can potentially
exceed 200 p.s.i. (14 KG/CM
2
)as tool may fracture or burst, possibly causing injury.
OPERATING PRESSURE:
Do not exceed recommended maximum operating pressure as tool wear will be greatly increased. The air supply
must be capable of maintaining the operating pressure at the tool. Pressure drops in the air supply can reduce the
tool’s driving power. Refer to “TOOL SPECIFICATIONS” for setting the correct operating pressure for the tool.
FILTER:
Dirt and water in the air supply are major causes of wear in pneumatic tools. A filter will help to get the best
performance and minimum wear from the tool. The filter must have adequate flow capacity for the specific
installation. The filter has to be kept clean to be effective in providing clean compressed air to the tool. Consult
the manufacturer’s instructions on proper maintenance of your filter. A dirty and clogged filter will cause a pressure
drop which will reduce the tool’s performance.
LUBRICATION
Frequent, but not excessive, lubrication is required for best performance. Oil added through the air line connection
will lubricate the internal parts. Use STANLEY-BOSTITCH Air Tool Lubricant, Mobil Velocite #10, or equivalent. Do
not use detergent oil or additives as these lubricants will cause accelerated wear to the seals and bumpers in the
tool, resulting in poor tool performance and frequent tool maintenance.
If no airline lubricator is used, add oil during use into the air fitting on the tool once or twice a day. Only a few
drops of oil at a time is necessary. Too much oil will only collect inside the tool and will be noticeable in the
exhaust cycle.
COLD WEATHER OPERATION:
For cold weather operation, near and below freezing, the moisture in the air line may freeze and prevent tool
operation. We recommend the use of STANLEY-BOSTITCH WINTER FORMULA air tool lubricant or permanent
antifreeze (ethylene glycol) as a cold weather lubricant.
CAUTION: Do not store tools in a cold weather environment to prevent frost or ice formation on the tools
operating valves and mechanisms that could cause tool failure.
NOTE:
Some commercial air line drying liquids are harmful to “O”-rings and seals – do not use these low
temperature air dryers without checking compatibility.

EYE PROTECTION which conforms to ANSI specifications and provides protection
against flying particles both from the FRONT and SIDE should ALWAYS be worn by the
operator and others in the work area when loading, operating or servicing this tool. Eye
protection is required to guard against flying fasteners and debris, which could cause
severe eye injury.
The employer and/or user must ensure that proper eye protection is worn. Eye protection
equipment must conform to the requirements of the American National Standards
Institute, ANSI Z87.1-1989 and provide both frontal and side protection. NOTE: Non-side
shielded spectacles and face shields alone do not provide adequate protection.
BEFORE HANDLING OR OPERATING THIS TOOL:
I. READ AND UNDERSTAND THE WARNINGS CONTAINED IN THIS MANUAL.
II. REFER TO “TOOL SPECIFICATIONS” IN THIS MANUAL TO IDENTIFY THE
OPERATING SYSTEM ON YOUR TOOL.
1. TRIGGER OPERATION
A TRIGGER OPERATED tool requires a single action to drive a fastener. Each time the trigger is pulled the tool
will drive a fastener. The trigger operated model is intended for use only when a contact trip or sequential trip
cannot be used due to the requirements of the application.
2. CONTACT TRIP OPERATION
The CONTACT TRIP MODEL tool contains a contact trip that operates in conjunction with the trigger to drive a
fastener. There are two methods of operation to drive fasteners with a contact trip tool.
A. SINGLE FASTENER PLACEMENT: To operate the tool in this manner, first position the contact trip on
the work surface, WITHOUT PULLING THE TRIGGER. Depress the contact trip until the nose touches
the work surface and then pull the trigger to drive a fastener. Do not press the tool against the work
with extra force. Instead, allow the tool to recoil off the work surface to avoid a second unwanted
fastener. Remove your finger from the trigger after each operation.
B. RAPID FASTENER OPERATION: To operate the tool in this manner, hold the tool with the contact trip
pointing towards but not touching the work surface. Pull the trigger and then tap the contact trip
against the work surface using a bouncing motion. Each depression of the contact trip will cause a
fastener to be driven.
There are three available systems on STANLEY-BOSTITCH pneumatic tools. They are:
1. TRIGGER OPERATION 2. CONTACT TRIP OPERATION 3. SEQUENTIAL TRIP OPERATION
The operator must not hold the trigger pulled on contact trip tools except during fastening
operation, as serious injury could result if the trip accidentally contacted someone or
something, causing the tool to cycle.
Keep hands and body away from the discharge area of the tool. A contact trip tool may
bounce from the recoil of driving a fastener and an unwanted second fastener may be
driven, possibly causing injury.
3. SEQUENTIAL TRIP OPERATION:
The SEQUENTIAL TRIP MODEL contains a contact trip that operates in conjunction with the trigger to drive a
fastener. To operate a sequential trip tool, first position the contact trip on the work surface WITHOUT PULLING
THE TRIGGER. Depress the contact trip and then pull the trigger to drive a fastener. As long as the contact trip
is contacting the work and is held depressed, the tool will drive a fastener each time the trigger is depressed. If
the contact trip is allowed to leave the work surface, the sequence described above must be repeated to drive
another fastener.

BASIC TOOL OPERATION
Stanley-Bostitch pneumatic tools are cycled by a compressed air operated single piston design. The following illustrations
show the four functional cycles that occur when the tool is operated to drive a fastener:
MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.
CAUTION:
Pusher spring (constant force spring). Caution must be used when working with the spring assembly. The spring
is wrapped around, but not attached to, a roller. If the spring is extended beyond its length, the end will come off the roller
and the spring will roll up with a snap, with a chance of pinching your hand. Also the edges of the spring are very thin and
could cut. Care must also be taken to insure no permanent kinks are put in the spring as this will reduce the springs force.
REPLACEMENT PARTS:
STANLEY-BOSTITCH replacement parts are recommended. Do not use modified parts or parts which will not
give equivalent performance to the original equipment.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE or equivalent on all “O”-
rings. Coat each “O”-ring with “O”-LUBE before assembling. Use a small amount of oil on all moving surfaces and pivots.
After reassembly add a few drops of STANLEY-BOSTITCH Air Tool Lubricant through the air line fitting before testing.
AIR SUPPLY-PRESSURE AND VOLUME:
Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of undersize fittings
and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent the tool from
receiving an adequate volume of air, even though the pressure reading is high. The results will be slow operation,
misfeeds or reduced driving power. Before evaluating tool problems for these symptoms, trace the air supply from the tool to
the supply source for restrictive connectors, swivel fittings, low points containing water and anything else that would prevent full
volume flow of air to the tool.
